desura is a development,release and cdn platform created by the team of moddb, Like steam with primary focus for indie games and free mods. And no you are not bound to one publisher.
www.desura.com Looks pretty cool, while we do not plan on doing mods, as most mods you need the permission of the original developer to post for sale there is no reason to not publish with as many publishers as you can. This can only potentially bring in more revenue.
